My invention relates to hinges for the lidsor covers of sewing-machines and the like.

The object of the invention is to provide a hinge .which will lie flush with the surface of the table-top and its lid-cover when the lid ment with said top and when it is swung down upon the upper face of the table-top. Th s object I accomplish by the construction shovn in the accompanying drawings, inwhich Figure 1 is a perspective of the hinge with its leaves in horizontal alinement or fully open. I Fig. 2 is a like view with the movable leaf swinging up perpendicular to the stationary leaf. Fig. 3 is a side elevation with the. movableleaf swung over upon the stationary leaf. Fig. 4 is a side elevation showing the leaves and their connecting members sepa-.

rated. Fig. 5 is a longitudinal central sec tion on hne '5 5, Fig. 1. Fig. 6 is a lan of the hinge fully open, parts being bro en away.

l ig. 7 isa side elevation of a portion of a machine-top and its lid with the lid fullyopenin full lines and its other positions in dotted lines; and Figs. Sand 9 are detail views of the recessed portion of the top and the lid-cover.

A designates the movable leaf and B the stationary leaf of the hinge. The stationary leaf B is formed of a horizontal attachingplate I), having at its one edgea depending the thiclmess ofthe table-top to which it is to be applied, and this flange is shaped to conform to the shape of the edge of the top ,which in the present case is an ogee. The memhers l'; b of the leaf B are let in flush with the upper and end surfaces of the top H; as The late bis formed with a rectangular opening coinciding. with an opening it, out in the end of the top H, and the side walls of the openin 71- are provided with vertically-disposed inc ined or curved flange b, the width of which is approximately,

recesses 7t, for a purpose tobe scribed. The under side of the eaf'B-is pro,-

vid'ed in the angle formed by- 'the two platesb with knuckles 6 The movable member A of the hinge is formed suhstantiallylike the leaf B and comprises the attaching-plate a, formed with a rectangular opening anda flange a, shaped to conform to-the shape of flange h and with the shape of the end of he swinging lid orcover l. The lower edg? the flangea is bent parallel with the plat a, as shown at c*, soas to overlap the surface of v the swinging lid or cover I. The said 1 lid or cover is recessed to receive the leaf A flush therewith.- The leaf A is formed or provided on its under side with elongated. knucklesio which'arc midway the ends of plate a; and the lower of the plate cat the edge of thecpening c farthest from the flange or, is beveled as at a and across this heveledsurface projects a guide li or, tongue at 1 C is a connectingp ate closely fitting the opening (t -and provided onits under side ator near onegend with-knuckles 9 which regis tel-with the elongated knuckles o and carry a transverse pintle c, which slides in said knuckles at. I The opposite edge of the connecting-plate is provided with knuckles c, which register with the knuckles b on leafB,

tle 0 The two leaves E are'thus held in swinging sliding relation instead ofheing di rectly hinged together.

presently do to which they are hinged by a transverse pin- C is a hinged extension of connecting-;

plate 0 and has a knuckle c-- extending be tween the knuckles c and mounted to swing on the pintle c": The extension C is of a size to close the opening b in plate 6 when the table lid or'cover I is swunginto horizontal alinement with the table-top H. The extension 0 is actuated ,from connectingp late C b means of atongue 0 which projects from plateC into a recess 0", formed theknuckle' c of extension (1. The free end-of the extension C is providedon its lowersidefwith a stop or sto s 0?, which projects into the'recesses h o opening it and engage the-lower side of plate 1; when the extension C is swung u by tongues to close-the'openingli in patebofleafB. When the leaf A is swung up from ,alinement with leaf B, the extension C 'rlro s down through opening I) and the leaf A sli es on the pintle 0 (see Fi 2) and hangs down, while the leaf A comp etes its movement to the position shown in Fig. 3. It will be seen that in this position the two leaves A B lie close one upon the other, and so permit the lid or cover I to lie down fiat upon the machine-top H. In the opposite movement of the lid or cover, or from the'position shown in Fig. 3 to that shown in Figs. 1 and 6 and by fu lines in Fig. 7, the tongue 0 will lift the extension G into the opening b until the stops 0'' engage the under side of plate b. Durin such movement of the lid its ogee edge will engage and slide alon the like edge of top H, and the leaf A wil' slide on pintle 0 until the lid is in alinement with the to whereuponplate a will be brought perfectly flush with connectin -plate C. The pintled edge of connectin plate C will during these movements slide etween the beveled edge a and the tongue a. When the hinge is fully 0 en, the hd I will be strongly sup orted, as t en the upper edge of flange a wi 1 engage the plate 0 near its pintle 0 while the apposite pintle 0 will firmly su ort the mid- 'e portion of the leaf A. oreover, the abutting o ee' edges ofthe lid and table will be forced closely together and so held by the pintle c, which then reaches the limit of its movement in the elongated vknuckles a The lates a b and the flange a are a erture for the attaching-screws. It wil be seen that any 0 enings in the exposed surfaces of the tabF-top and lid are fully covered at all times by the leaves of the hinge and that all exposed portions of the hinge are fliis'l with the surfaces to which they are ap- 1e P The im roved hinge is designed especially for the Ii 3 employed with drop-head sewingmachines; but they may be employed in any other relations without departing from the spirit of my invention.

Having thus described my invention, what I I claim, and desire to secure by Letters Patent, is-- 1. A hinge comprising a pair of leaves hav ing registering openings, a connecting-plate slidingly hinged at its outer edge to the under side of the movable leaf to close the opening therein and hinged at its inner edgelto the adjacent edge of the stationary leaf, a second swingin plate closing the opening in the stationary eaf and means for actuating the said swinging plate from the said connectingplate.

2. A hinge comprising a pair of leaves hav; ing registering openings, a connectin -plate closing the opening in the movable eaf, a swinging plate forming a hinged extension of the connecting-plate to close the opening in the stationary leaf when the two leaves are horizontally alined, a sliding connection-between the under side of the movable leafand the outer end of the connecting-plate and a pintle connecting the connecting-plate and its hinged extension, to the under side of the fixed leaf adjacent to the abutting edges of the two leaves, and means for actuating said hinged extension.

3. A hinge comprising a pair of leaves having registering openings, a connecting-plate slidingly connected at its outer end to the under side of the movable leaf and filling the opening therein when the two leaves are a ined; the inner end of the said connectingplate being hin ed to the under side of the adjacent edge 0 the stationary leaf, a swinging extension actuated from the hinged end of the said connecting-plate to close the opening in the stationary leaf, and a stop on the said extension to engage the under side of the stationary leaf.
